For POSH Treatment, Heat Map
Basic heat-mapping guided cabin selection for Victorian travelers sailing from Britain to India. The resulting acronym, POSH – port out, starboard home – defined a level of comfort for an era. Do your strawberries, medicines, high end electronics and other products receive the posh treatment they deserve, or are they placed randomly and exposed to potentially harmful temperature variables? Without heat-mapping, you may never know.
Shippers and carriers are learning that, for sensitive goods, placement matters. As they temperature-map their warehouses, planes, and trucks, they’re finding temperature variations based upon time of day, season, air flow, and air handling equipment. Proactive shippers and carriers are beginning to use temperature monitors to develop a heat map of their facilities and cargo spaces to identify the best and worst positioning for sensitive cargo.
Take a warehouse, for example. To map that environment, temperature monitors should be placed top to bottom, left to right, front to back, and where variations are likely (near loading dock doors, for example). With such a monitoring grid, it’s easy to map the temperature gradation between the floor and ceiling, or between inner and outer walls. Such information also spurs insights into the adequacy of air handling systems, thermostat placement, and placement of shelves, racks, and pallets in relation to air flow.
Heat mapping applies to transportation, too. Packages along trucks’ outer walls are influenced by outside temperatures and gaps in insulation. Improperly loaded cargo may impede air flow, or refrigeration equipment may be faulty. Live monitoring is even possible, so problems can be solved before damage ensues. After a heat-mapping exercise, expect to have a thermal image of the space showing hot and cold spots, multi-season comparisons, and thorough documentation of the environmental conditions and variations throughout the study. Temperature mapping is most effective as a recurring part of an on-going strategy to the occurrence of temperature excursions.
